Fixed

• Admin rebuild notice now shows exactly once after rebuild (replaced query-param approach with 60-second transient)
• CLI --indexer flag now correctly falls back to the admin setting default when the flag is absent

Added

• "Test Connection" button in the AI settings panel (LLM endpoint + API key verification)

Changed

• Inherits all scolta-php 0.2.3 fixes and features (filter sidebar, N-set merge, AI context, PII sanitization, priority pages)
